I imagined that condensation should not be a problem. The Geiger counter was in a ~27 - 30°C environment before I went into the (quite a bit colder) basement. I would have to think of something to keep it at those higher temperature throughout the measurement, maybe a hair dryer?
Cooling...
It could well be, if the radon or its decay products somehow stuck to my clothes or something. But wouldn't the reading change depending on how close I am to the detector?
As I've said, I think that is unlikely. The radon would have to spread across multiple floors, through several doors, and...
I tried to find a good radon-map for my area, the best I could find lists the radon concentration of the air near the ground as '41-100 kBq/m^3', which is the second highest category. I am not really sure what that compares to in other parts of the world because the map only showed Saxony.
No...
I can't really imagine how it should be trapped inside the detector. I even tried to blow air across the detector to replace any possibly contaminated air with no effect. But if I find some time I will do a more controlled experiment and write down the values, maybe this will us something.
It...
Only due to the high humidity, but no drops of water or something like that. I tested this a second time this morning, paying extra attention to not touch any surface with the Geiger counter, not holding it in the hand I touched any of the walls before, removing any spider webs in the way etc...
Hi everyone! I'm new to this forum, so I hope my question fits into this category.
Yesterday I wanted to check if I could measure any radiation from Radon in my basement with my Radiascan-701 Geiger counter which features a pancake-style probe that should be able to handle alpha, beta and...
